| Bioactivity | Biotin-XX hydrazide (Biotin-(AC5)2-hydrazide) is a carbonyl-reactive biotinylation reagent which contains two aminohexanoic acid spacers. Biotin-XX hydrazide has higher efficiency of avidin-binding[1]. |
| Invitro | Biotin-XX hydrazide contains two aminohexanoic acid spacers which greatly enhances the efficiency of formation of the complex between the biotinylated antibody (or other biotinylated protein) and the avidin–probe conjugate, where the probe can be a fluorochrome or an enzyme[1]. |
